And again someone giving false info. IMU should not be calibrated unless the devices asks for it (confirmed several times by DJI, doing it might even make things worse) I have never done it since I have mine, just keep an eye on the sensors before takeoff.
Doing compass-calibration is also a bad thing if you don't know what you are doing. For example: In my home, when I have mine on the floor, it will scream MAGNETIC INTERFERENCE due to cables under the floor. When I lift it, it is gone, so I don't care about that. This is why, when you get a compass error, you should not immediatly calibrate, as when you will be airborn, the compass will return normal with a good calibration. There is no metal in the air! So doing a compass calibration with interference under the floor without knowing it, might give a good compass on the ground but a BAD ONE in the air as the conditions change, suddenly no metal/interference. So I lift off about 2m in the air. Check compass, if all are at minimum, I fly.

True. Bought a P4P recently and right out of the box it flew perfectly. No calibrations needed - still hasn't ask for it either.
